Description
Technical field
The utility model belongs to machinery manufacturing technology field, is related to a kind of gear, more particularly to a kind of anti-slip gear.
Background technology
Gear be on wheel rim it is with teeth can continuously engage transfer movement and power mechanical organ, be mainly used in transmission shaft and
In gearbox, primarily served in transmission shaft power transmission effect, in gearbox, using multi-stage gear combination by the way of come
Realize the function of speed-changing gear box speed change.Due to gearbox limited area, many gears all save sky using fabricated structure
Between, it is composed of large diameter gear and small-diameter gear, the built up gear on existing market is mostly just using integrally formed
Method fabricates, due between gear there are stress difference, caused by the degree of wear also can be different, built up gear
In any one gear failure when can all cause it is whole scrap, lead to problems such as use cost increase.
For this problem, many manufacturers take up to improve gear, by monoblock type made into can
The detachable gear wheel of combination is dismounted, but due to relatively simple for structure, in prolonged work, is caused due to vibrations etc.
The generation of loose phenomenon can send noise, and the slippage of gear can be caused when serious, influence the normal work of equipment.
The content of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, and peace can flexibly be dismantled by providing one kind
The anti-slip gear that dress, performance are stablized.
The purpose of this utility model can be realized by following technical proposal：A kind of anti-slip gear, including large diameter gear
And small-diameter gear, the outer end of the large diameter gear and small-diameter gear are both provided with the gear teeth along part, which is characterized in that described
The groove of the gear teeth is distributed along the axis direction of gear, and the small-diameter gear lower end has optical axis section, the optical axis section one side
With outwardly protruding connection convex block, the fixed groove with small-diameter gear splicing cooperation, institute are offered on the large diameter gear
The fixed groove bottom side stated has the connection groove penetrated for being coupled convex block, and the connection groove bottom is provided with release
Groove, the large diameter gear are provided in the axis hole also cross big with offering axis hole at small-diameter gear center
The connecting shaft of footpath gear and small-diameter gear.
The technique effect of this anti-slip gear：The fixed groove to cooperate with small-diameter gear is offered on large diameter gear,
Have on small-diameter gear and be coupled convex block, fixed groove bottom side has the connection groove penetrated for being coupled convex block, is coupled groove
Bottom is provided with release groove, and when assembling gear, small-diameter gear Gear tipping is placed, along connection groove with discharging groove
It is inserted at port in release groove, until the optical axis section other end is entered in fixed groove, ajusts small-diameter gear, be coupled convex
Block slides to connection groove out of release groove, and then by connecting shaft two gears are attached with fixed completion assembling.
In above-mentioned anti-slip gear, the width of the release groove is wider than the width for being coupled groove.Discharge groove
During wider width, small-diameter gear can be helped when mounted, release groove is caught in the angle of inclination of bigger, then will be coupled convex
Block, which slips into, to be coupled in groove.
In above-mentioned anti-slip gear, the marginal portion of the connection convex block is provided with the chamfering of arc-shaped.It prevents
Scuffing of the sharp edge to gear recesses surface, while arc-shaped chamfering plays a guiding role, it is suitable that help is coupled convex block
Profit, which imports, to be coupled in groove.
In above-mentioned anti-slip gear, the axis hole opened up on the large diameter gear and small-diameter gear is located at same axis
On.The assembly precision between connecting shaft and large diameter gear, small-diameter gear is improved, promotes stability during built-up gear operating.
Compared with prior art, this anti-slip design of gears, which has, is coupled groove and release groove, discharges groove by designing
It can will cleverly be coupled convex block to be inserted into connection groove, and not only realize the assembling of large diameter gear and small-diameter gear, be also less prone to
It slips, has the advantages that flexibly to remove and install, performance stabilization.

Specific embodiment
It is specific embodiment of the utility model and with reference to attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these embodiments.
As shown in Figure 1, this anti-slip gear, including large diameter gear 1 and small-diameter gear 2, large diameter gear 1 and small-diameter gear
2 outer end is both provided with the gear teeth 3 along part, and the groove of the gear teeth 3 is distributed along the axis direction of gear, and 2 lower end of small-diameter gear has
Optical axis section 4,4 one side of optical axis section have outwardly protruding connection convex block 5, offer on large diameter gear 1 and match somebody with somebody with the splicing of small-diameter gear 2
The fixed groove 6 of conjunction, 6 bottom side of fixed groove have the connection groove 7 penetrated for being coupled convex block 5, are coupled 7 bottom of groove and set
Release groove 8 is equipped with, large diameter gear 1 is provided in axis hole 9 also cross big with offering axis hole 9 at 2 center of small-diameter gear
